In spiral model the main emphasis is on the management to evaluate and resolve risks in the software project. There is no maintenance phase in spiral model because instead risk is evaluated .
engineering phase
Not all models of software engineering are risky. The spiral model takes care of risk in every phase.
In the third or maintenance phase, the patient is relatively stable and can be kept indefinitely on antipsychotic medications. Even in the maintenance phase, however, relapses are not unusual
Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.
In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.

1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.

The incremental model is a software development approach where the project is divided into smaller increments or iterations. Each iteration delivers a portion of the final product, allowing for incremental development and testing. The spiral model is a risk-driven approach where the project is divided into multiple phases, with each phase including risk analysis and mitigation. The spiral model combines elements of both iterative development and waterfall model, allowing for flexibility and risk management throughout the project lifecycle.
The waterfall model is a linear model that follows a sequence as activities move from one to another. The spiral model is a circular model that breaks software development into smaller segments.
There are generally six stages, requirement analysis, design, implementation, testing, deployment and maintenance. Analysis is where the requirements are laid out so that the design phase can figure out how to best implement them. Implementation is where most of the work happens, leading to black and white box testing. After the testing phase, the product is rolled out to customers, and the maintenance phase is ongoing from that point on.
Conditioning Phase
Only during the maintenance phase
The phase of change diagram, also known as the Transtheoretical Model of Change, is a framework that outlines the stages individuals go through when making a behavior change. It consists of five stages: precontemplation, contemplation, preparation, action, and maintenance. This model helps individuals understand where they are in their change process and how to progress towards making lasting changes.
Not sure
The testing phase consumes the maximum effort in waterfall model.
